     On March 2, 2007, Converium Holding AG included the following statement on
its website, including a hypertext link to the press release issued by Standard
& Poor's on February 28, 2007, which is set forth on page 3 of this Schedule
14D-9:

     Converium's financial strength is currently followed by a number of rating
agencies including S&P, Moody's, Fitch and A.M. Best. Please note that any
opinions, estimates or forecasts regarding Converium's historical or predicted
financial strength or performance made by these rating agencies are theirs alone
and do not represent opinions, forecasts or predictions of Converium or its
management. Converium is providing the attached press release as a service to
its stockholders, and does not by so doing imply its endorsement of or
concurrence with such information, conclusions or recommendations. Interested
persons must obtain copies of rating agencies' reports on their own; Converium
does not distribute these reports.

Additional information and where to find it:

     In connection with the offer by SCOR, Converium expects to file a
solicitation/recommendation statement with the Securities and Exchange
Commission (the "SEC"). Investors and security holders are strongly advised to
read these documents when they become available because they will contain
important information about the tender offer and the proposed merger. Copies of
the solicitation/recommendation statement will be available free of charge at
the SEC's web site at www.sec.gov, or at Converium's website at
www.converium.com.

Swiss Reinsurer Converium AG And
Subsidiaries Ratings Raised To 'A-'
And Taken Off Watch Pos

Rationale

On Feb. 28, 2007, Standard & Poor's Ratings Services raised its long-term
counterparty credit and insurer financial strength ratings on Switzerland-based
reinsurer Converium AG and its long-term insurer financial strength ratings on
guaranteed operating entities Converium Rueckversicherung (Deutschland) AG and
Converium Insurance (U.K.) Ltd. to `A-' from 'BBB+'. At the same time, Standard
& Poor's removed these ratings from CreditWatch, where they had been placed with
positive implications on Oct. 17, 2006. The outlook on all entities is stable.

     The upgrade reflects Standard & Poor's belief that the group (Converium)
will eventually settle with regulators on transactions subject to regulatory
inquiries, and it will do so at a cost that is not material to our view of group
capitalization. This follows analysis of a recent independent study commissioned
by Converium of settlements of SEC investigations. The study examined
settlements in more than 100 cases between July 30, 2002, and Feb. 20, 2007.
Settlements in cases involving groups with a market capitalization of $5 billion
or less ranged from $0-$50 million. Although the cost of a settlement is as yet
not certain, Standard & Poor's believes that Converium's capital adequacy would
remain consistent with that of the current rating level, even in the event of a
settlement considerably in excess of the upper limit of the indicated historical
range.

     The ratings reflect the group's strengthened management team and sound
infrastructure, strong competitive position, and strong capitalization. These
positive factors are partially offset by current earnings that are good but
currently lower than what would be expected for the rating as well as the
relatively low barriers to entry of the reinsurance industry.

Outlook

The stable outlook reflects Standard & Poor's expectation that the combined
ratio for the group will be less than 100% in 2007 and the ROR will be in excess
of 10%. Controlled premium growth is expected over the next couple of years,
market conditions permitting. Most growth will be generated by the recovery of
shares on existing treaties lost as a result of cedents previously reducing
their exposure to the group or from the return of old clients. Capital adequacy,
as measured by Standard & Poor's risk-based model, will remain strong.

     An outlook revision to positive is unlikely in the medium term, and would
depend on the group significantly outperforming targets over a sustained period.
The outlook would likely be revised to negative, however, if one or more of the
following events were to occur:

|X|  SCOR S.A. (foreign currency A-/Stable/-, local currency A-/Stable/A-2) is
     successful in its unsolicited bid, leading to potential integration risks
     such as Converium seeing significant loss of key staff and/or support from
     its key European client base.
|X|  Unexpected material legacy costs arise in relation to loss-reserve
     strengthening, regulatory sanction, or shareholder litigation.

Major Rating Factors

|X|  Standard & Poor's believes that the group's infrastructure is sound.
     Management action since 2004 has largely addressed previous operational
     shortcomings, though controls have yet to be tested over a prolonged period
     of time. Converium has benefited from additional infrastructure investment,
     the refocusing of roles following senior management reorganization, and the
     experience acquired through recent senior hires.
|X|  Converium's competitive position is strong. Standard & Poor's believes that
     despite past financial difficulties, the group has maintained the support
     of key cedents. Long-term relationships, the material use of a direct
     distribution model, and strategic partnerships (particularly within
     specialty business lines), add competitive strength. The relatively low
     barriers to entry of the reinsurance industry partially offset these
     strengths.
|X|  Capitalization is strong, supported by strong capital adequacy, an
     aggregate claims reserve position enhanced further following the sale of
     discontinued North American operations at the end of 2006, limited
     retrocession dependence, and generally strong quality of retrocessionaires.
|X|  Good nonlife operating performance is expected to be primarily driven by
     sustained improvement from continuing nonlife operations and supported by
     attractive underwriting conditions, limited volatility with regard to
     legacy liabilities, and a reconfigured group expense base. The key
     determinant of nonlife earnings in the longer term will be the speed at
     which premium rates soften, Converium's cycle management response, and the
     successful execution of group strategy.
